I

The preferred form of construction as lllustrated in the drawings comprises a table or supporting frame consisting of a top 40v and supporting legs 41. Arranged below the table top 40 substantially midway the extremities thereof is a transversely extending "shaft 42 mounted in suitable bearing brackets 43 which depend from said table top. At one end of the shaft 42 is provided a pulley 44 around which passes an endless belt 45 for effecting driving of the machine, the belt 45 being driven through the medium of any iukitable power supply such as a motor or the 1 e. 1 Arranged at the front end of the table below the top 40 is a receiving mechanism or or trough intowhich the packages are deposited in the introduction thereof into the machine for wrapping. This trough comprises an endless belt 46 which travels around rollers 47 and47. The. roller 47 is intermittently rotated to effect intermittent feeding of the packages by the belt 46 by means of a rocker arm 48 which is connected at its outer end by means of a link 49 with the lower end of a rocker arm 50 fixed at its upper end to a transversely extending shaft 51 mounted in the bearing brackets 43. Connected with the arm 50 is a link 52 which carries a roller 53 which engages an irregular camgroove 54 provided ina cam disk 55 which is fixed to the shaft 42. The free end of the link 52 is provided withan elongated slot, as clearly shown in Fig. 2, which loosely engages the shaft 42, the latter thereby serving as a means of retaining said end of said l1nk in operative position, permitting of longitudinal movement there of such as is incidental to rotation of the cam 55. With this arrangement it will be seen, that upon rotation of the cam disk 55, the rocker arm 50 will be oscillated causing corresponding movement of the rocker arm 48. The rocker arm 48 is operatively connected with the roller 47 through the medium of a conventional.paWl-and-ratchet mechanism 56 so that upon oscillation of the arm 48 the belt 46 will be intermittently moved in only one direction, as will be readily understood. The bottom of the package receiving trough is constituted by the upper side of the belt 46, the sides of the trough being formed. by spaced elongated members 57 which are rigidly connected and from the respective extremities of which depend bearings for the rollers 47 and 47 as illustrated. The trough is removably supported in position by a tongue 58 provided at the inner end thereof which engages a slot 59 provided in a channel member v62 which depends from the under side of table top 40, hooks or latches 60 provided at the opposite sides of the member 62 releasably engaging eyes 61 provided at the outer sides of the corresponding ends of the minbers 57 to releasably lock the trough in position, as will be readily understood. With this arrangement, it will be seen, that if desired or if it becomes necessary to disconnect the trough .in order to afford access to other parts of the mchanism for adjustment or repair, it

is only necessary to disconnect the link 49 from the arm 48 and then to release the hooks or latches 60.

. In the operation of the machine the packages introduced to the receiving trough will be conveyed inwardly in the latter by the belt 46 until said packages abut the adjacent side of the member 62, a plate 63 being provided at the inner bight of the belt to prevent the packages falling through the space intervening the roller 47 and the member 62.

Mounted for vertical sliding in the member 62 is a package elevating member 64 provided at its upper end with a horizontally extending flange or ledge 65. The flange 65,

when the member 64 is at its lower terminal of movement, will be positioned below the plate 63 and so that upon upward movement of said member 64, the innermost pack age, or that which is positioned in proximity with the member 62 will be engaged by the flange 65 and carried upwardly thereby, as clearly shown in Fig. 4, a package. A being shown positioned upon said flange. Vertical reciprocation of the member 64 as mentioned, is effected through the medium of a link 66 pivotally connected at its upper end with the lower extremity of said member 64, the lower terminal of said link being connected with one end of a bell crank lever 67 which is fulcrumed at 68. The other extremity of the lever 67 is provided with a roller 69 which contacts with the periphery of a cam 70 fixed to the shaft 42. The arrangement is such that, upon rotation of said cam, the bell crank lever 69 will be oscillated to effect vertical reciprocation of the package elevating member 64, as desired. The amplitude of reciprocation of the member 64 is such that a package A elevated thereby will be passed or forced between two spaced spring-pressed rollers 72 and 72, as clearly shown in Fig. 4.

Arranged at the forward end of the table is a rectangular wrapper magazine 73 open at its upper side, said magazine'being adapted to accommodate a large number or plurality of wrappers arranged one above the other in stack form. The rearward end of the magazine 73 is pivotally supported upon inwardly projecting pins 74 secured to elongated frame members 75 which are secured rigidly to the table top 40, as clearly shown in Figs. 4 and 18; The front end of the magazine 73 is supported by a "ertically slidable plate 76 mounted in. the table top 40 the upper edge of which engages against the under side of a laterally projecting lug 77 provided at one side of the magazine 73 at the front end thereof, as clearly shown in Figs. 4, 18 and 25. The plate 76 is secured to the table top 40 by means of screws 78 which pass through el ngated slots 7 8 'provided in the plate 76, the arrangement being such that, upward rocking of the front end of the wrapper magazine may he effected by vertically moving said plate 76. Such movement of the plate 76 is secured through a rocker arm 79 the lower or outer end of which engages against the lower edge of said plate. Said rocker arm 79 is fixed to a transversely extending shaft 80 which is rockingly mounted in suitable bearings. as shown in Figs. 25 and 26. Said shaft is rocked by means of a rocker arm 81 the outer end of which is connected with a link 82 which carries a roller 83 engaging a cam groove 84 provided in one side of a cam disk 85 which is fixed to the shaft 42. Said cam groove is of such formation that, upon rotation of the shaft =12, the link 82 will be reciprocated to causeoscillation of the arm 81, the end of said link bearing the roller 83 being longitudinally slotted for engagement with the shaft 12 inorder to utilize the latter in maintaining said end of said link in operative position, as will be readily understood. The rocker arm 81 is operatively connected with a collar- 86 splined to the shaft 80, by means of a conventional pawl-and-ratchet mechanism 86', the arrangement being such that, upon oscillation of said arm 81, the shaft will be rotated in only one direction or in such a direction as to cause upward-rocking of the arm 79 to effect intermittent elevation of the plate 76 and hence of the forward end of the wrapper mechanism 73. In the operation of the machine, the arm 7 9 will be-rocked down wardly by gravity. 'By splining the collar 86 to the shaft 80, the operative connection between the rocker arm 81 and said shaft may be broken by simply moving said collar, longitudinally upon said shaft to such an extent as to move the ratchet formed upon said collar out of operative relation with the pawl which is mounted upon said arm 81.

Arranged below the wrapper magazine 73 is a pasting mechanism. the forward end of the table top 40 being cut away in order to receive said pasting mechanism. Said pasting mechanism comprises a tank 87 which is removably supported in position by channel members 88 provided at the lateral walls thereof which slidably engage flanges 89 provided at the adjacent edges of the opening of the table top, as clearlyshown in Figs. 4 and 18. Mounted in the tank 87 is a roller or cylinder 90 through which extends a square shaft 91, one end of said shaft 91 projecting laterally through.

the corresponding edge portion of the table top to permit of removal of said shaft when it is desired t8 release the tank 87 so as to permit .of removal thereof, as will be read-' ily understood, said shaft being held in position through friction. The arrangement is such as will be observed by reference to Fig. 33 that, upon removal of said shaft the tank 87 will be free for outward sliding upon the to the hub 95 of a rocker arm 90. said hub being loosely mounted upon said sleeve. Provided at the outer end of the arm 96 is a spring-pressed pawl 97 adapted for ensides of the fi a'me members 75.

gagement with a ratchet 98 formed upon the peripheryof a collar 99 which is splined to said sleeve, as shown. The arrangement is such, as will be observed, that upon oscilla tion of the gear 91 the arm 96 will be correspondingly oscillated to cause intermittent rotation of the collar 99 and hence the sleeve" 92, shaft 91 and roller 90. By sliding the collar 99 upon the sleeve 92 to such an extent as to position the ratchet 98 out of operative relation with the pawl 97' the opera t-ive connection between the arm 96 and-the roller 90 may be broken, and so that during operation of the machine, cessation of operation of said roller may be effected bysimply sliding the collar 99 as mentioned. A shifting-fork 100 fulcrumed at 101 Cooperates with said collar forinoving the same i into or out of operative position.

Oscillation of the gear 91 to effect intermittent rotation of the'pasteroller 90, as

described, is secured through a rack formed -at the under side of one of two bars 102 which are slidably mounted in elongated grooves or channels103 formed-at the inner Said rack meshes with the gear'9-1 whereby, upon reciprocation of the members, 102, said gear will be oscillated as desired. T he'members 102 at the opposite sides of the machine'fare connected, as clearly shown in Figsfl 9 and 20, by av tran"s\-'erselyf extending plate 101 the respective extremitiesv of which arerigidly connected to said' members 102.

In the operation of the machine the under side of the forward edge ortion of the lowermostof the wrappersvarranged in the magazine 73 will normally project through the outlet opening73 at the front end of the magazine into contact with; the upper side ofthepastemoller 90, and ,so'that upon rotation of said roller as just described. paste will be applied to said forward edge portion of the-lowermost wrapper. A gage 87 arranged atithe upper edge of'the paste tankQ87' cooperates, with the roller 90 to control the quantity of paste which is carried by the peri hery of said .roller in the rotation thereo Disengage-- ment of said edge ofsaid wrapper from said roller in order to permit of the engagement thereof by the gripping mechanism to be hereinafter described, is secured through the employment of a rectangular wire member 105 the opposite parallel side portions of which are 'slidably mounted in guide loops 106 which are secured upon the under side of the magazine 73. Said member 105 is so arranged that, upon forward movement thereof. the front transverse bar portion of said member will pass between the front'edge portion of the lowermost wrapper B and the roller 90 and force said edge portion of said wrapper from engagement with the periphery of said roller. Reciprocation of said wrapper disengaging member which engage elongated slots in said plate,

as clearly shown in Figs. v23 and 24 The arrangement is such, that upon reclprocation of said plate 111, the lever 107 will be oscillated to cause operative .movement of the member 105. Projecting from the plate 111, as clearly shown in Figs. 18 and 23 1s a stud 113, the adjacent side ofthe table top being provided with an elongated slot 114 to permit of the passage of said pm. Said pin is engaged by the outer end of a rocker arm 115 which is fixed to a shaft 116 mounted insuitable bearings 117, the outer end of said arm 115 being provided with-an elongated slot for engagement with the pin 113, so that upon oscillation of said arm saidpin and hence the plate 111 will be recipro- 116 is an arm 118 with the outer end of cated. Loosely mounted upon the shaft which is connected a link 119, said link, as clearly shown in Fig. 23, carrylng a roller 120 which engages a cam groove 121 provided in one side of a cam disk 121 secured to the shaft 42. The arrangement issuch that, upon rotation of the shaft 42, the l nk 119 will be reciprocated to cause osc llat on of arm 118, the end of said link bearing the roller 120 being longitudinally slotted for engagement of the shaft 42 1n the same manner and for the same purpose as other links heretofore described.' Splined to the shaft 116, as shown in Fig. 18, 1s a collar 122 which is operatively connected with the rocker arm 118 by means of a conventional pawl-and-ratchet mechanism. 123, the arrangement being such, that, upon osclllation of arm 118, as just mentioned, the shaft 116 will be intermittently moved in one direction to cause operative or forward movement of the wrapper disengaglng member 105. A helical tension spring 124 coiiper ates with the plate 111 to effect retrograde movement thereof and hence .of the member 105. By splining the collar 122 upon the shaft 116, as mentioned, the operative connection between the arm 118 and said shaft may be broken by sliding said collar to move the ratchet formed thereon out of registration with the pawl which is carried by said arm. in the same manner as above described relative to the vertical movement of the front end of the wrapper magazine and the rotation of the paste roller. A switch fork 125 fulcrumed at 126 cooperates with the collar 122 for sliding the same into or out of operative position.

Arranged at the inner end of the package receiving trough is an oscillatory blade 127 the respective extremities of the stem 128 of which are mounted in bearings provided at the upper edges of the trough side members 57, as clearly shown in Fig. 18. Cooperating with the blade 127 are helical tension springs 129 which are so arranged as to serve to normally hold the blade 127 in depending vertical position. 'Said blade is so positioned that packages passing through the trough will engage against the former and cause the same to be rocked upwardly to substantially horizontal position against the influence of the springs 129, as clearly shown in Figs. 1,2 and 4. The arrangement is such that in use, the blade 127 will be normally held in elevated position by reason of the presence of packages inthe receiving trough, and that upon the exhaust of the supply of packages in said trough, said blade will be swung downwardly under the influence of the springs 129. Provided at the respective ends of the stem 128 are cranks 130 and 131. The crank 130 is connected by means ofa link 132 with one end of a bell crank lever 133 which is fulcrumed at 13 1, as clearly shown in Figs. -18 and 33, the opposite end of said bell crank lever being connected by means of a link 135 with the switching fork 100. The arrangement is such that, upon downward rocking of the blade 127, as just mentioned, the incidental rocking of the crank 130 will cause oscillation of the switching fork 100 to move the collar 99 to inoperative position and thus break the operative connection between the driving mechanism of the machine and the paste roller 90. The crank 131 is similarly connected by means of a link 136 with a bell crank'lever 137 which is fulcrumed at 138, as clearly shown in Figs. 25 and 26. Said bell crank lever is connected by means of a link 139 with a shifting fork 140 which engages with the collar 86. The arrangement issuch that, upon downward rocking of the blade 127 as mentioned, the incidental movement of the crank 131 will effect oscillation of the fork 140 to cause shifting of the collar 86 to inoperative position'and hence to destroy the operative connection between the driving mechanism of the machine and the plate 76 which is adapted to impart vertical movement to the front end of the wrapper. magazinc. The outer end of the crank 131 projects into engagement with the lowermost of the slots 7 8' provided in said plate 76. The lower endportion of said slot is provided with a notch 78" as shown in Fig. 25 to permit of oscillation of the crank 131, said I venting contact of the wrappers with the paste roller. v 4

The crank 131 is also connected by means of a link 141 with a bell crank lever 142 fulcriuned at 143 ,as shown in Figs. 18,23 and :26. The bell crank lever 1&2 is connected by means of a link 144 with the shifting fork 125 whereby said fork will be openated to cause shiftingot the collar 122 to inoperative position upon downward rocking of the blade 127. With this arrangement then it will be seen that, upon the supply oi packages in the machine becoming exhausted, the mechanism which is instrumental in withdrawing the wrappers for application to the packages and which is instrumental in applying the paste to said wrappers will be automatically stopped al though the remainder of the machine still continues to operate.

The wrapper withdrawing mechanism comprises a gripping device arranged at the imder side of the transversely extending plate 101, as clearly shown in Figs. 1. 19 and 20. Said gripping device .comprises cooperating jaws 145 and 146, said jaws being provided with rearwardly projecting fingers 145' and 146" respectively which pivotallv engage a transversely extending rod 147 mounted at the under side of plate 104. Opening movement of the jaws-145 and 146 is secured through the medium of a transversely extending bar 148 which is rockingly mounted in bearing members 1-19 formed at the under sides of the fingers 145', as clearly shown in Figs. 4 and 22. The bar 148 is provided at its ends with cranks adapted for'engagement against the under sides of the fingers 146'. the arrangement being such that. when said bar is oscillated, the engagement of said cranks against the under sides of the fingers 146' will cause the latter to he swung upwardly and hence the jaw 146 to be correspondingly moved upwardly into operativer'elation with the jaw 145,,as clearly shown in the figures above referred to. Also. the arrangement is such that, when the bar 148 is rocked in the opposite direction the cranks thereof will move from engagement with the under sides of the fingers 116' and permit the jaw 1-16 to move 'doivnwardlv' to open position bv gravity. The respective extremities of the bar 148 engage upon the inclined upper edges of guide 'bars 148. the latter thus serving as a'means of retaining the jaw members in proper elevated positions for engagement with the forward edge of the lowermost wrapper in the wrapper magazine, when said jaw members are movedtoward the same.

Actuation of the bar 148 is efiected through the medium of a locker arm 150 secured to-the member 148 medial1y of the ends thereof. The arm. 150 is connected at its lower or free end with a rearwardly projecting operating bar 151, longitudinal movement of the bar 151 causing corresponding movementof the plate 104 and hence of the bars 102=to=eifect operation of the paste roller as above;. described. The arrangement is such that, upon forward movement of the bar 151 in order to effect actuation of the paste roller 90, the bar 148 will be rocked in such a. direction as to effect release of the fingers 146' to permit of downward or opening movement of the jaw 146, as above mentioned, and, upon rearward or return movement of the bar 151, the arm 150 will cause rocking of the member 148 to rock the fingers 146' upwardly and hence to move-the jaw 146 into operative relation with the jaw 145. Hence, with the construction set forth, it will be seen that opening of the gripping mechanism is automatically eflected upon forward movement of the bar 151, and closingrof said mechanism secured upon rearward or return movement ofsaid nal of movement, the same will be adapted to engage the forward edge of the lowermost wrapper B arranged in the magazine '73.

The machine is so adjusted that in operation the wrapper disengaging member will he moved to disengage the forward edge of the lowermost wrapper, as above described, just before the gripping jaws arrive at their forward terminal of movement. Also, the mechanism is so timed that the upward rocking of the forward end of the magazine 73 occurs just before the disengagement by the member 105 of the forward edge of the lowermost wrapper, this upward rocking of the magazine serving to elevate the forward edges of the other wrappers Bfrom engagement with the corresponding edge of the lowermost wrapper, and so-that, when the latter is released from the paste roller by the disengaging mechanism 105, said forward. edge thereof will be positioned substantially medially between the periphery of the paste roller and the forward edges of the remaining wrappers in themagazine so as to permit of ready engagement thereof by the gripping jaws-145 and146. Said gripping scribed, until the same reverse their movement, at which time said jaws, in moving to closing position, engage the forward edge of the lowermost wrapper to cause withdrawal thereof from the magazine when said jaws are moved from said magazine. The cam groove 84 in the cam 85 is so formed as to effect release of the forward end of the magazine 73 and hence downward movement thereof immediately upon the withdrawing movement of the gripping jaws and so that in the withdrawing of the wrapper, the under side of the latter will contact with the periphery of roller 90 which will apply paste thereto as will be readily understood.

If it is desired to apply paste to only the end portions of the under side of the Wrapper instead of to the entire surface such as is the case where a cam having a cam groove of the shape of the groove 84 is employed, a cam 85 having a cam groove 84, as shown in Fig. 27, may be used. The cam groove 84 is so formed as to cause the front end of the magazine 73 to be held in elevatedposition until the wrapper is almost completely removed when said end of said magazine will be lowered. This being so paste will be applied to only the front and rear edge portions of the wrapper,

none being applied to the central portion thereof or while the front end of the magazine is in elevated position.

The wrapper B which is withdrawn by the gripping mechanism from the wrapper magazine is carried to the position shown in Fig. 4 directly over the package A which I is positioned upon the flange 65 of the package elevating member 64 and so that, upon further upward movement of the package by said member 64, the wrapper will be folded over the two sides thereof through contact of the rollers 72 and 72 with the wrapper. The package will be momentarily held elevated by the flange 65 in position directly above the rollers 72 and 72 until a transversely extending plate 153 engages against the front face of the package to effect advancing thereof along the table to complete the folding of the wrapper about the package. The plate 153 is provided at its lower edge with a flange 153' which is adapted upon operative movement of said plate to engage the edge portion a of the wrapper and cause the same to be folded against the corresponding edge portion of the under face of the package as clearly ShOWfl'I in Fig. 34. The plate 153 is carried by a transversely extending bar 154 the re spective ends of which are secured to bars 155 which are slidably mounted in longitudinally extending grooves 156 provided at the inner sides of the guide members 75. Reciprocation of the bars 155 is secured by links 157 which are connected with arms 158 which are fixed to the shaft 51, the arrangement being such that, upon oscillation of the shaft 51 such as is caused through reciprocation of the link 52 by means of the cam 55, said arms 158 will be oscillated to cause actuation of the bars 155, as will be readily understood.

In the operative movement of the plate 153 the package will. be moved over the roller 72 and slid onto the upper sides of longitudinally extending supporting strips or bars 159. In the passage of the package over the roller 72 edge portion 1) of the wrapper will be folded into engagement with the under side of the package, as clearly shown in Fig. 34, the package being advanced by the plate 153 to a position substantially centrally upon the supporting members 159.

The rearward end of the bar 151 is pivotally connected with a. transversely extending bar 160, as clearly shown in Figs. 19, 20 and 21. The transversely extending bar 160 serves as a yoke which connects longitudinally extending bars 161 which are mounted for slight longitudinal movement at the underside of a plate 162 which is mounted for reciprocatory movement between channel guides 163, the guides 163 being supported upon supporting brackets 163 mounted upon the table top 40. Carried by the plate 162 are two sets of engaging fingers 164 which are "pivoted at 165 in slots 164provided in said plate. The lower ends of the fingers 164 are connected with bars 161, the arrangement being such that, through longitudinal movement of said bars, said fingers may be swung to vertical position as shown, or to horizontal position in the slots 164. Reciprocation of the plate 162 is secured by a link 166 which is connected at its rearward end with the outer extremity of a rocker arm 167 secured to a shaft 168 mounted in suitable bearings 168 depending from the table top 40. The shaft 168 is rocked by an arm 169 which is connected with one end of a link 170, the opposite end of said link being provided with a roller 171 which engages a cam groove 172 provided in a cam disk 173 which is fixed to the shaft 42, as clearly shown in Figs.a-4 and 5. The arrangement is such that, upon rotation of the cam disk 173, the shaft 168 will be oscillated to cause corresponding rocking of the arm 167 and hence reciprocatory movement of the plate 162. The connection of the bars 161 with the fingers164 is such that, upon movement of the link 166 to effect sliding of the plate 160 toward the left, said fingers 164 will be rocked downwardly to horizontal or inoperative position, and that,
